I've only heard the term "deflection" used for a situation where a piece is enticed or forced from the defense of a key square/diagonal/rank/file. I would guess "decoy" means the same thing but isn't as widely used.

Edit: Actually according to wikipedia, a decoy is when you lure a piece to a specific bad square, whereas a deflection lures it to any square where it can no longer adequately defend. So a decoy would be a specific type of deflection (if I understood it correctly).

Thats how I understood it when I learned it. Decoying gets a piece to a bad square, generally to capture it later in the line. Deflection just gets them away from defense of a key square/rank/diagonal, not necessarily to put it in danger, but to take advantage when the piece is overloaded, as the Black Queen is on this puzzle.

Checkmate was inevitable. I would have taken the queen and hoped the other guy/gal made a blunder...ha ha. Actually, now that I look at it again, by taking the queen on the first move, it would have set up a defence for when the pawn promoted. Game would have continued....
